Bosch Super 4 Spark Plugs
Has anybody used these? are they any good and has anyone noticed any power gain or problems. My TT 225 is due for a plug change was thinking of changing over to these.

yeah i had em in my chipped a4, they were ok, didnt notice any power gain ive just got some denso iridium jobbies, which are meant to be the nuts, allthough ive not noticed any performance gain, the car feels much more responsive, on part throttle, got em of ebay 4 39 quid, which is cheap as they are meant to be 16 each.
